Take a look at: http://www.cmake.org/Wiki/CMake_Useful_Variables In your case CMAKE_SOURCE_DIR may do what you want. You can create a project configuration file and use #cmakedefine and CONFIGURE_FILE() to create defines to use in your source file. That would provide you with a fixed location, suitable for the build you are running now. What is the purpose of the resources.txt. Is this something you need during the creation of your executable? Or do you need it during the execution of the program? Regards, Micha
